In this post, let’s look at what’s tested in the chapter heat capacity and latent heat in O Level Physics. This topic on heat capacity and latent heat is a topic under thermal physics, and is the chapter with quite a number of calculation questions.
Watch the video here to find out what’s tested in this topic.
Below, you’ll find a checklist on the items you would need to know on this topic on heat capacity and latent heat.
Checklist for O Level Physics Topic: Transfer of thermal energy
✓ how a change in temperature is related to a change in internal energy
✓ definition of heat capacity (C) and specific heat capacity (c)
✓ Use the formulae Q = mc Δθ and Q = C Δθ
✓ describe melting, freezing, condensation and boiling in terms of change in average potential energy (but not average kinetic energy) of particles, resulting in temperature remaining constant
✓ differences between boiling and evaporation
✓ define latent heat and specific latent heat (l)
✓ Use the formula Q = ml
✓ Interpret a cooling or heating curve
